[ 1/1 Equation]
Work: Find the solution of equation 198.376+0.86×a-77.98×2 = 7485.92 .
Question type: Equation
Solution:Original question:
24797 125 | + | 43 50 | a | − | 3899 50 | × | 2 | = | 187148 25 |
| Left side of the equation = | 24797 125 | + | 43 50 | a | − | 3899 25 |
| = | 5302 125 | + | 43 50 | a |
5302 125 | + | 43 50 | a | = | 187148 25 |
Transposition :
43 50 | a | = | 187148 25 | − | 5302 125 |
Combine the items on the right of the equation:
43 50 | a | = | 930438 125 |
The coefficient of the unknown number is reduced to 1 :
| a | = | 930438 125 | ÷ | 43 50 |
| = | 930438 125 | × | 50 43 |
| = | 930438 5 | × | 2 43 |
We obtained :
| a | = | 1860876 215 |
Convert the result to decimal form :
| a | = | 8655.237209 |
